Anxiety can be service-connected. The connection has to be documented.

Yes. If onset can be tied to service — through records, stressors, or a diagnosis during service — anxiety can be claimed directly. If not, it may be claimed as secondary to another service-connected condition.

Anxiety disorders are rated under the General Rating Formula for Mental Disorders (0, 10, 30, 50, 70, or 100%), based on occupational and social impairment — not on the specific diagnosis.

Anxiety and PTSD are usually rated together under the same mental-health rating rather than separately, but a nexus letter can support increases or clarifications where symptoms have grown.

Anxiety commonly follows chronic pain, TBI, tinnitus, or a life-changing injury. That is a classic secondary-service-connection pathway and a well-reasoned nexus letter is often what carries it.

Yes. Chronic pain and physical limitations can cause or aggravate anxiety by creating persistent worry, sleep disruption, loss of independence, fear of reinjury, reduced activity, financial stress, and uncertainty about future functioning. Service-connected orthopedic injuries, migraines, neuropathy, respiratory disorders, gastrointestinal conditions, and other chronic illnesses may contribute to clinically significant anxiety. The medical opinion should explain how the veteran's particular symptoms, limitations, and disease course contributed to the development or worsening of the anxiety disorder.

Yes. Persistent tinnitus may contribute to anxiety through sleep disruption, impaired concentration, irritability, hypervigilance, emotional distress, and the inability to escape the perceived sound. Some veterans become increasingly preoccupied with the tinnitus or fearful that it will worsen, which can lead to panic symptoms, social withdrawal, or difficulty tolerating quiet environments. A nexus opinion should apply these mechanisms to the veteran's documented tinnitus severity, symptom history, treatment, and functional impairment.

Yes. A nexus letter may help when the VA denied the claim because it found no medical connection between the anxiety and military service or a service-connected condition. The opinion should directly address the stated reasons for denial, evaluate unfavorable C&P findings, discuss relevant medical and lay evidence, and explain why the veteran's history supports service connection. A new medical opinion may potentially be submitted as new and relevant evidence with a Supplemental Claim.

Yes. Panic attacks may support a higher evaluation when their frequency, severity, and functional effects contribute to greater occupational and social impairment. Relevant consequences may include missed work, avoidance of driving or public places, inability to travel independently, emergency room visits, impaired concentration, disrupted sleep, or dependence on family members. Panic attacks are only one part of the disability picture, however, and the VA should consider the veteran's complete pattern of symptoms and impairment.

Veterans may be diagnosed with both anxiety and PTSD, but the VA generally does not assign separate ratings for overlapping mental health symptoms. Instead, the VA typically evaluates the overall level of occupational and social impairment produced by the service-connected psychiatric conditions. A separate diagnosis can still be clinically important, particularly when it clarifies symptoms that are not fully explained by PTSD or establishes a different pathway to service connection.
